Hello sandeep Welcome to Health Care Magic The sudden onset attacks of unconsciousness especially in morning are alarming. They may occur due to following possible reasons- One thing is hypertension, kindly get your Blood Pressure checked as due to postural hypotension in a hypertensive person sudden fall may occur. But it doesn t occur repetitively. Other possibility is Seizure Disorder. In epilepsy or seizure multiple loss of unconsciousness may be observed even without typical movements of extremities. In most of cases cause can not be established and MR scans and EEG come normal. Start of Anti Epileptic Drug is advised like Valporate sodium, carbamazepine, phenatoin etc. These are to be taken for long time (usually at least 3 years as per guidelines). You were on valporate chrono 300 twice a day and you are now taking 300 per day. Valporate in a lot of people during initial phases of therapy may cause nausea, vomiting, dizziness as side effects. Due to this appetite ultimately decreases. But decreasing dose against the advise of doctor is not advised. The problems of lack of understanding, confusion, memory loss etc don t occur with valporate at 300 per day. It is therwise safe drug. So as per my opinion kindly visit a good Psychiatrist and take advise on epilepsy and the clinical symptoms you are having, don t stop medication abruptly against advise.
